摘要： The invention provides an electronic device for acquisition of a dummy paging message. In an embodiment, the electronic device comprises a dummy pattern generator, a receiver, and a paging channel handler. The dummy pattern generator provides a first artificial pattern according to a previously received result corresponding to a dummy paging message. The receiver receives a first burst for a paging message. The paging channel handler controls the receiver to recover a first data content for the paging message according to the first burst and the first artificial pattern, determines whether the first data content represents a dummy paging message, and directs the receiver not to activate to receive remaining bursts for the paging message when the first data content represents a dummy paging message. The dummy paging message is employed for synchronization between a mobile station comprising the electronic device, and a serving base station.

摘要： A synchronization circuit includes a correlator, an energy calculator, a post-processing unit, and a decision device. The correlator correlates a received sequence r(t) with a local sequence c(i) to obtain a correlation result h(t). The energy calculator calculates an energy function of the correlation result h(t), and filters the energy function of the correlation result by a channel impulse response wc(l) to obtain a filtered energy function e(t), where l is the index of the channel impulse response. The post-processing unit applies weighting function wa(t) to the filtered energy e(t) to obtain a weighted energy function e′(t), wherein the weighting function wa(t) weights a central portion of the filtered energy function e(t). The decision device selects a maximum energy value from the weighted energy function e′(t), and the time index t with maximum energy value is the time shift of the received sequence and the local sequence.

摘要： The invention provides a method for frequency offset estimation according to a filtered signal with destroyed phase information. In one embodiment, a filter filters an original signal according to a series of first filter coefficients to obtain a first-channel component of the filtered signal, and filters the original signal according to a series of second filter coefficients to obtain a second-channel component of the filtered signal. A series of third filter coefficients are first derived from the first filter coefficients. The original signal is then filtered according to the third filter coefficients to obtain a reference signal. A first frequency offset value is estimated according to the first-channel component of the filtered signal and the reference signal, wherein the first-channel component of the filtered signal is a first-channel component of an artificial signal, and the reference signal is a second-channel component of the artificial signal.

摘要： An apparatus and method for frequency synchronization is proposed to obtain the pilot tones and evaluate the frequency offset and time offset for frequency synchronization. The frequency synchronization method has the following steps: filtering a baseband signal of a frequency correction burst by using multiple pre-filters; measuring the baseband signal and the signals output from the pre-filters to produce the first power value and the second power values respectively; normalizing the maximum second power value by using the first power value so as to produce the first detection value; using the samples of the baseband signal at different time points and a predetermined mathematical function to produce the second detection value; combining the first and second detection values to produce the third detection value; and using the third detection value to determine whether the frequency correction burst is received or not.
